Optical-fibre sensors have been developed for the determination of blood gases and pH. Chemical binding of pyrenebutyric acid and 7hydroxy-4-methylcoumarine-3-acetic acid to a porous tip of a fused silica fibre produces a sensitive measuring device for molecular oxygen and pH. Insertion of the pH se
